did you get stuck the same way as i did? i though shade means to stay near some wall where there appears to be a little bit of shade, but i passed that part already, myself
as in shade you have to look for the parts on the map that looks to be below geound like a crevice type area. I got stuck since i got a black screen covering like 8 blocks wide on the right and left side of the map so i had to randomly search in the black screen area for the way.
i yhink shade is considered a darker area close to a wall or a crevice areas. Tho shade is only used in the dessert area so thats like the best explaination i know
